[98] He called the Paris talks a fraud without “no deeds, only promises” and believes that only an interterritorial tax on CO2 emissions, which is not part of the Paris Agreement, would reduce CO2 emissions fast enough to avoid the worst effects of global warming. [98] Carbon dioxide, salmon gas and methane are gases that accumulate in the atmosphere and prevent heat from spreading from the Earth`s surface into space, which produces what is known as the greenhouse effect. According to the Intergovernmental Panel on Climate Change (IPCC), the main international scientific body dealing with this issue, the concentration of these heat-capturing gases has increased significantly since a pre-industrial period and has risen to a level that has not been reached for at least 800,000 years. Carbon dioxide (the main cause of climate change) has increased by 40% since 1750, salmon gas by 20% and methane by 150%, mainly due to the burning of dirty fossil fuels. The IPCC says it is “extremely likely” that these emissions are mainly responsible for the rise in global temperatures since the 1950s. Meanwhile, deforestation and forest degradation have also contributed to their fair share of global carbon emissions. Instead of giving China and India a passport on pollution, as Trump claims, the pact represents the first time these two major developing countries have agreed on concrete and ambitious climate commitments. Both countries, already ready to let the world lead renewable energy, have made considerable progress in meeting their Paris targets. And since Trump announced his intention to withdraw the U.S. from the deal, The leaders of China and India have reaffirmed their commitment and continued to implement domestic measures to achieve their goals.
